Type.

SOUTH AUSTRALIA, Cudnaka [Kanyaka], Mueller s.n. (holotype MEL; isotypes MEL, P!).

Description.

Perennial herb with trailing stems to 1 m, vegetative parts covered in long, whitish appressed velvety hairs, densely so on young growth. Leaves dimorphic: leaves of non-flowering shoots long-petiolate, 1-2 × 0.6-1.5 cm, ovate-deltoid, rounded, margin serrate, base truncate (very rarely slightly auriculate) and shortly cuneate onto the petiole, petiole 1-2 cm; leaves of flowering shoots 1-1.5(-2.5) × 0.5-1.4 cm, ovate-deltoid in outline but deeply toothed and incised towards the base; petioles 0.2-0.8 cm. Flowers solitary, pedunculate, axillary; peduncles 0.3-0.8 (-1.2)cm, becoming recurved in fruit; bracteoles linear c. 1 mm; pedicels 1-3 mm; outer sepals 4 × 3.5 mm, elliptic, apiculate, the point recurved, sericeous; inner sepals similar but with fewer hairs; corolla 5-6 mm long, white or pink, lobed with somewhat triangular lobes, midpetaline bands sericeous; ovary glabrous, style glabrous, divided 2-2.5 mm above base; stigmas c. 1.5 mm. Capsule glabrous; seeds slightly winged and with low irregular sinuate ridges. [ Johnson 2001: 15-19, f. 5-6, map 4]

Distribution.

Australia: Southern South Australia and adjacent parts of Victoria and New South Wales ( Alcock 652, Kuchel 1470, Chinnock 2915, Hill et al. 5426). Johnson (2001) cites Copley 571 but this looks like an error for Convolvulus eyreanus as the peduncles are 1.5-2 cm long and mostly bear two flowers while the leaves are not so strongly sericeous.

Notes.

This species shares with Convolvulus eyreanus a dense indumentum of longish appressed hairs. Fruiting specimens can be recognised by the short recurved peduncles bearing single flowers, small capsules (4-4.5 mm in diameter) and small seeds (<3 mm long).
